solaris "last" command does not give year information in output

Hi,
there is a perl script (a one-liner) which could help you formatting the lastlog file closer to your needs.
http://www.hcidata.info/lastlog.htm
Some modifications may be necessary, but it's rather clearly explained on the page I pointed you to.
Good luck!
wmp

#!/usr/bin/perl
#this finds the most recent year for which the day matches the date
use POSIX;
@d{qw(Sun Mon Tue Wed Thu Fri Sat)}=(0..6);
@m{qw(Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec)}=(0..11);
$r=qr/\b(@{[join'|',keys %d]})\s+(@{[join'|',keys %m]})\s+(\d+)/;
while( <> ){
    s#$r#
      my $w=$d{$1};
      my $m=$m{$2};
      my $d=$3;
      $y=(localtime)[5];
      --$y while (localtime mktime(0,0,12,$d,$m,$y))[6] != $w;
      strftime("%d/%m/%y",0,0,12,$d,$m,$y)
    #e;
    print;
}

If it is the current year, Solaris doesn't show it in dates by default.  Same is true for day typically.  If the date it is displaying is the same as the current date, typically only the time is shown.

#!/usr/bin/perl
#this finds the most recent year for which the day matches the date
use POSIX;
@d{qw(Sun Mon Tue Wed Thu Fri Sat)}=(0..6);
@m{qw(Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec)}=(0..11);
$r=qr/\b(@{[join'|',keys %d]})\s+(@{[join'|',keys %m]})\s+(\d+)/;
while( <> ){
    s#$r#
      my $w=$d{$1};
      my $m=$m{$2};
      my $d=$3;
      $y=(localtime)[5];
      --$y while (localtime mktime(0,0,12,$d,$m,$y))[6] != $w;
      strftime("%d/%m/%y",0,0,12,$d,$m,$y)
    #e;
    print;
}

first perform the #uptime if ur server started above 1yr you will get the year info otherwise it will give you the month and date information only.
